Abstract:

Eleven tomato genotypes were crossed in Line ×Tester fashion to develop 33 hybrids, which, along with their parents and check were evaluated for earliness, fruit yield and quality of tomato (Solanum lycopersicum) to know extent of combining ability for the same. The lines P-7 (-4.990) and P-8 (-2.990) were found to be the best general combiner with significant highest GCA (General Combining Ability) in desirable direction for days to 50% flowering while P-4, for days to first ripening (-6.47), no. of fruits per plant P-6 (170.80) was best general combiner. P-3 was exhibits significant GCA in desirable positive direction for avg. ten fruit weight (11.08), total soluble solid (0.60) and texture (0.76). In case of yield per plant the lines P-10 (0.61) and P-11 (0.43) showed positive significant GCA while, P-5 for flesh thickness. The tester P-13 (mutant) was a best general combiner for traits like days to Days to first ripening (-4.77), No. of fruits per plant (127.60) and Total soluble solid (0.27), whereas, P-12 was found best general combiner for No. of fruits per plant (126.15) Texture (0.14). The crosses viz., P-4 × P-14 (9.74), P-1 × P-14 (6.71) and P-7 × P-12 (6.52) were found to be superior specific combiners for fruit yield per plant. Cross P-8 × P-14 was a superior specific combiner for fruit quality traits like flesh thickness (0.75), total soluble solid (1.06) and texture (0.28). On the basis of superior GCA and SCA for earliness, yield and quality of the crop, suitable genotypes may be identified which can be used in further breeding programs.
